a picture has dimensions of 5 cm by 10 cm. IF you want to enlarge the picture to a size of 32 1/2 cm x 65 cm by what fraction would you multiply the dimension
Picture 1: 5 by 10 Picture 2: 32.5 by 65 Divide two lengths or two widths. 65/10= 6.5 That is the ratio. To check, multiply the width of Picture 1 by the ratio and see if it gives you the second picture's width. 5 x 6.5=32.5 Hope this helps.
